Green tea (Camellia sinensis) has attracted significant attention in both scientific and consumer communities due to its health benefits against a variety of disorders. Catechin and epigallocatechin gallate (EGCG) are the most abundant polyphenols in green tea. They have been studied for their therapeutic potential in various cancers, Alzheimer's disease, obesity, and diabetes. However, catechin and EGCG have limitations for use in foods, feeds, and pharmaceuticals due to their low solubility, easy degradation, instability in alkaline conditions, and low permeability. Catechinand EGCG-glucosides have higher water solubility compared to catechin and EGCG, respectively. They are also resistant against alteration of color (to a yellowish brown). This chapter summarizes enzymatic transglycosylation for producing novel catechinand EGCG-glucosides. Biopharmaceutical properties (such as water solubility, stability in solution, and biological activities) and structural activities of these glucosides are also discussed.
